Wavelet analysis is used in direct thrust control system of linear motor drive in this paper. The change of the primary resistance of linear motor will greatly affect the performances of direct thrust control system at low speeds. The observation of flux linkage is improved by accurate identification of primary resistance, and the direct thrust control performance of linear motor is further improved...
This paper introduces that in the move-mode processing of traditional numerically controlled machine, friction exists between the moving parts and the still guide rail. So we propose a brand-new method to eliminate the friction by utilizing the magnetic suspension linear motor. Experimental result indicates that non-friction control can be achieved, and under the action of a moving object can conduct...
We employ the special function of wavelet transform that can extract the characteristics of singular signals, as to the thrust fluctuation in the direct drive linear servo system, to process wavelet analysis and research on the thrust fluctuation in permanent-magnet synchronous linear motor servo system, and it finally proves that we can observe the velocity variation of a machine tool worktable by...
